Note:

 To gain better access to components, remove 

the wires that plug onto the large relays on the 
Relay Board. (See

Relay Board

.

) Cut the wire tie that 

the Smart Board

 

CN103 wire harn ess (See 

Smart

Board

.) is routed through. 

Check voltage between Smart Board CN102 pins 10 
and 12. 

•  If 5 VDC is present, check the harness between 

the Smart Board and Glass Touch Assembly. If 
OK, replace Glass Touch Assembly and Smart 
Board.

•  If 5 VDC is not present, replace the Smart 

Board.

If the Backlight (Monogram Only) is not working:

Check to see if the Buzzer is working.

•  If Buzzer is not working, the Smart Board is 

not supplying Buzzer and backlight operating 
voltage. See 

Smart Board

 Troubleshooting 

Section.

•  If Buzzer is working, replace Smart Board and 

Glass Touch Assembly.

Disassembly

To remove the Glass Touch Assembly:

1.  Disconnect power to the oven.

2.  Remove the control panel assembly.
       (See 

Control Panel Removal

.)

3.  Remove the Relay Board.
       (See 

Relay Board Removal

.)

4.  Remove the Smart Board.
       (See 

Smart Board Removal

.)

5.  Remove the VFD Board.
       (See 

VFD Board Removal

.)

6.  Remove the Selector Board.
       (See 

Selector Board Removal

.)

Glass Touch Assembly

•  Part of the control panel assembly.

•  Converts user touch to electrical signals.

•  Has nothing to do with the display.

•  Requires 5 VDC from Smart Board. Voltage can 

only be checked between Smart Board CN102 
pins 10 and 12.

•  Contains the back light (Monogram only).

Troubleshooting

If some keys are working:

Check the harness between the Smart Board and 
Glass Touch Assembly. If OK, replace Glass Touch 
Assembly and Smart Board. 

If no keys are working:

Disconnect Smart Board connector CN15. Re-test 
Glass Touch Assembly.

•  If keys are working correctly, replace the 

Selector Knob.

•  If keys are not working correctly, continue to 

next check.
